In Oregon, age is a part of the public accommodations law. This means that stores cannot discriminate against someone because of their age. Tobacco, marijuana, and alcohol are exceptions.

"I see this going to summary judgment," said Max Whittington, Watson's lawyer. "I don't think there's a lot of facts at issue. I think that the courts will agree with us that these practices are discriminatory and enjoin them."

Whittington said the stores are ignoring Oregon law and need to be held accountable.

He said his client would only accept a settlement "if [Dicks and Walmart] would reverse their policy and stop these discriminatory practices."

Whittington hasn't been contacted by the NRA or any other gun rights groups about the lawsuit.

"At this time, we are not looking for any support for anyone," he said.

The Bureau of Labor and Industries sent a letter to the president of the Oregon Senate and Speaker of the House about the bill it plans to introduce next season. It would change Oregon's current law to include firearms on the list of exemptions.
